[Machine] On the authority of the Prophet ﷺ , he said: "There is no deed more pure in the sight of Allah, the Mighty and Majestic, and no deed more deserving of rewards than a good deed performed during the ten days of Dhul-Hijjah." It was asked, "Not even Jihad for the sake of Allah?" He replied, "Not even Jihad for the sake of Allah, except for a man who went out with himself and his wealth and did not return with anything." It is reported that Sa'eed ibn Jubayr would exert extreme effort and strive his best during the ten days (of Dhul-Hijjah) to the extent that he could barely manage it.  

عَنِ النَّبِيِّ ﷺ قَالَ «مَا مِنْ عَمَلٍ أَزْكَى عِنْدَ اللَّهِ ﷻ وَلَا أَعْظَمَ أَجْرًا مِنْ خَيْرٍ يَعْمَلُهُ فِي عَشْرِ الْأَضْحَى» قِيلَ وَلَا الْجِهَادُ فِي سَبِيلِ اللَّهِ قَالَ «وَلَا الْجِهَادُ فِي سَبِيلِ اللَّهِ ﷻ إِلَّا رَجُلٌ خَرَجَ بِنَفْسِهِ وَمَالِهِ فَلَمْ يَرْجِعْ مِنْ ذَلِكَ بِشَيْءٍ» قَالَ وَكَانَ سَعِيدُ بْنُ جُبَيْرٍ إِذَا دَخَلَ أَيَّامُ الْعَشْرِ اجْتَهَدَ اجْتِهَادًا شَدِيدًا حَتَّى مَا يَكَادُ يَقْدِرُ عَلَيْهِ
